General

fixed files with periods (E.G; 'test.puzzle.pzl') not opening in the file dialog (Jared)

added missing frame/border detail to file dialog art

added support to toggle bilinear filtering/smoothing (read more below) (Will)

Updated file dialog at top; previous at bottom

If you prefer more pixelated graphics without bilinear filtering applied, set BilinearFiltering to false in your config file. The below image shows the difference between the two styles. Here are links to the full-sized images of bilinear and non-bilinear screenshots. This setting only applies when the game is running full screen and not in a window.
